Going back to your first email:
- B1 - bat0: 192.168.10.1/24 - default gateway: 192.168.10.2
- GW: bat0: 192.168.10.2/24, eth1: 192.168.20.2/24
- EX: eth0: 192.168.20.3/24 - default gateway: 192.168.20.3
You default GW on EX does not make sense. You cannot use yourself as a
default gateway. It needs to be a remote device. In this case, EXs
default gateway should point to 192.168.20.2.
However, you say ping works, so that does not explain your problem.
Check your firewall rules.
iptable -L
maybe one of the rules is causing the kernel to drop the packets.
